ga-990fxa-ud3 build questions II- Front panel Connectors

[ictoos]

Next Question

2) There are three USB connectors, the one on the far right is red, I've place the connector that came wired with the case into, but what do i do with the other two?  Do they HAVE to be hooked up or are these for expansion later?  I also have the USB connector to the right of the red hooked up as per the picture.

While we're in the neighborhood, just to check the TPM, COM port are for later expansion correct?  There is nothing to do with it right now unless I have a comm need(Which could be?) on an encryption need through the TPM.)

To the other side, I think I have the front panel connecters hooked up right and while I read that the orientation of the connector is not ALWAYS critical, the colored wire is POS and POS is left so I just standardized.  

I am a bit nervous about the orange(Speaker) in that there are four pins and the connector only have two female connectors to go on the male.  

Red-power, green- reset, and blue-HD activity all seem to be in order assuming my color on left orientation is OK

The grey is a security feature for case opening(Empty and understandable) and the lime green has no connector(upper left hand corner) Do I need to have this?

Apart from the power lead so that youi can start the system without having to put your hand inside the case each time the rest of the connections are totally optional. The power button doesn't matter which way around it is connected. The LEDs for HDD and power will need to be the correct way to work but you can do that by trial and error if need be.

Forgewt the TPM and com unless you need them. When you say speaker I take it that you have a piezo electric device. That will only work in the correct orientation but then again it won't hurt if the wrong way round. Also forget the case open connector and just make sure it is disabled in the BIOS.
